Description
Tests on materials already used or under development for beam intercepting devices were successfully completed by early October 2012 in the HiRadMat facility. A dedicated sample holder hosting six different materials was specifically designed and constructed for this project. Experimental data were acquired, mostly in real time, relying on extensive embarked instrumentation (strain gauges and temperature sensors) and on remote acquisition devices (laser Doppler vibrometer and high speed camera). The digital acquisition system had dynamic ranges sufficient to acquire the very fast and intense shockwaves generated by the impact. The high-speed video camera allowed capturing the material fragments projected away from impacted specimens. Preliminary results of this comprehensive, first-of-its-kind experiment will be presented. In particular the well documented examples of beam damage on materials can be useful viewing for machine operators. In depth post-irradiation analyses foreseen once the specimens have reached a sufficiently low level of activation will also be briefly outlined. Coffee / tea will be served after the seminar ATS Seminars Organisers: H. Burkhardt (BE) T. Stora (EN), G. De Rijk (TE)
